Abstract
We obtain sharp rotation bounds for homeomorphisms whose distortion is in , , and whose inverse have controlled modulus of continuity. The motivation to study this class of maps comes from so-called Yudovich solutions to planar Euler equations. Furthermore, we present examples proving sharpness in a strong sense, thereby settling the borderline case in \cite[Theorem 3]{CHS}.
